1. RECOMMENDATIONS AND SAFETY
SETPOINTS
Read the instructions in the manual carefully before starting to install the apparatus and keep the manual in good condition close to the apparatus
throughout its working life.
1.1 Individuel protection
• This apparatus can be used by children aged over aged 8 years and people with reduced physical, sensory or mental capabilities, or lacking in expe-
rience or know-how, (providing they) are properly monitored or are instructed in the safe use of the apparatus, and if any possible risks are clearly
understood.
• Children should not be allowed to play with the apparatus. User cleaning and maintenance must not be carried out by unsupervised children.
1.2 Installation and maintenance precautions
• Installation of an VEX unit can be dangerous due to moving or powered up components. This equipment should be installed, commissioned and
serviced by trained and qualifi ed personnel, observing Standards and standard good practices.
• All servicing or maintenance operations requiring the access doors to be opened or one or more components to be removed must be carried out by
a qualifi ed technician.
• All electrical connections to the equipment must carried out by a technician in accordance with requirements laid down in the NF C 15-100 Standard.
• In particular, a contact separation device with an opening of at least 3mm on each pole as well as a protection device with an appropriate rated
current should be installed in the inbuilt raceways (circuit breaker). Copper conductor sections are defi ned in sections 2.9.3, 2.9.4 and 2.9.5 of the
installation manual.
• The product must be powered down before any maintenance or cleaning operation.
• Make sure that the unit cannot be accidentally started up.
• To avoid any risk of accident, if a power cable is damaged it must be replaced by the technician who installed the product, or another qualifi ed
technician.
• In the event that the motor overheats, its linear modulation will be reduced. When it exceeds its maximum internal temperature, the controller powers
down the motor and restarts it automatically after cooling. In the event of motor failure (motor integrated circuit failure signal, phase failure, motor stal-
led, shorted to ground or internal short circuit, intermediary or network reduced or excessive voltage, peak current fault) an alarm triggers apparatus
power down. Disconnect power supply (circuit breaker on the electrical panel), check that nothing is restricting unit operation (e.g. blocking, friction,
clogged wheel, abnormal noise...) and wait one hour before powering up again.
• If the problem persists, contact your installer or dealer.
• Use only manufacturer’s original parts.
• For units fi tted with an electric heating coil: in the event of multiple failures in electrical coil power control (at least two sensors failed) and in case of
overheating in the air input chamber (Ambient temperature > 80°C), an automatic rearming thermostat triggers electrical coil shutdown. In addition,
the electrical coil is fi tted with a manual reset thermostat which triggers at 120°C and is located in a sleeve between the resistors.
• To maintain the guarantee, no modifi cations must be made to the apparatus.
• To ensure correct operation, the apparatus must be regularly maintained.
